Clinical Questions & Answers

Q1: Can I take sleeping pills while pregnant?

Do not take over-the-counter or prescription sleep aids unless explicitly approved by your doctor.

Q2: Is sleeping on my back safe in the third trimester?

Side sleeping is recommended. Back sleeping can compress the vena cava, reducing blood flow to the placenta.

Q3: How do I use a pregnancy pillow?

Place it under your head, run it along your back or stomach, and tuck it between your knees.
